Every team has its question marks going into Fall Camp, and Oregon is no exception. The Ducks have ten graduated seniors in NFL camps, yet were picked this week by college coaches and the nation's #3 team.[details]

Notes: Father, Clay, was a 19-year linebacker for the Browns and Falcons (1978-96); grandfather, Clay Sr., was a lineman for the 49ers in the 1950s; uncle, Bruce, was a Hall of Fame guard for the Houston Oilers/Tennessee Titans (1983-2001) and currently serves as an offensive assistant for the Titans; brother, Clay III, is a linebacker for the Packers and cousin, Kevin, is a center for the Titans. As a true freshman in 2007, Casey saw action in 11 games and was credited with 18 tackles, four for loss and one sack. Played all 13 games in '08, starting the final seven at middle linebacker, and recorded 67-13-2 with two pass breakups. In '09, started all 13 games and posted 81-4½-3 with five pass breakups and an interception. Missed the final two games with a shoulder injury. Started all 13 games at "Mike" linebacker in '10, posting 79-9-3 with three pass breakups, three interceptions and a forced fumble. Injured right shoulder performing bench press at the Combine.

Positives: Has keen eyes and instincts - triggers quickly and is very active. Pursues hard and angles are true - beats blockers to the spot. Has a nose for the ball and a knack for sifting through congestion. Tough and competitive. Showed up in the BCS national championship game, including forcing a fourth-quarter fumble from Auburn QB Cam Newton. Plays with a special-teams mentality. Terrific personal and football character - passionate about the game. Has superb NFL bloodlines.

Negatives: Is undersized and has short arms and small hands. His 13 reps of 225 pounds in the bench press was the lowest number amongst linebackers at the Combine but he did not complete testing because of shoulder injury. Average speed and athletic ability - can be a step late to the perimeter. Does not use his hands violently to disengage and can be subdued by larger blockers. Shows some hip tightness when required to break down in space. Not a punishing, explosive tackler. Inconsistent zone reactions. Poor hands. Has to be schemed free as a blitzer.

Summary: Intense, experienced, high-motor, football-smart linebacker who could be overdrafted because of his last name. That said, has broad appeal as a low-risk, relatively known commodity given his consistency, football temperament and production. His ceiling will depend on his ability to get bigger and stronger without sacrificing speed and movement skills. Should be a core special-teams player and push for a more prominent role for teams such as the Patriots, Chiefs, Lions or Seahawks.
